I am getting the following warning message when trying to use ftp_put():

This is causing the function to return false, when in fact the file is 

I have Googled this warning message but no one else has ever received it. Where 
this warning coming from and why is PHP reporting a "Transfer OK" as a warning?

I will give this a try when I get a chance. How long until these fixes are into a 
stable release?

I notice you added a check for the 200 response in ftp.c. This didn't fix the 
problem for me. But also adding a check for a 221 response did. Is it possible to 
have this added into the codebase too?

According to RFC #959 a 221 reply is supposed to only be possible
for a QUIT command[1].
